Abstract

Laminated glass windscreens etc. contg. a relatively rigid layer of transparent material of thickness between 0.125 and 6.3 mm, consisting of an original exposed surface, on which is applied, to form a new exposed face, a layer of optically regular polyurethane of thickness 0.75-3.8 mm, the new exposed surface to be directed to the interior of the structure in which it is to be installed. The polyurethane increases the resistance of the glass to bursting and abrasion following the shock of an object against the outside face of the window. The relatively rigid layer is pref. polycarbonate, and a sheet of glass or other transparent material may be interposed between the polycarbonate and the polyurethane layer. Used in armoured vehicles, aircraft cockpits etc.
